This is something I plan to place in my final TL...
The Lima Standard Series - Part 1
As the Diesel grew in prominence in the US, the Lima locomotive works decided it was time to try and beat the diesels at a key game. That is, producing locomotives that could be used by any railroad for most purposes. These locomotives would become known as standards by virtue of using the same designs for one engine used on all trains.
The first standards were relatively simplistic in their origins. All of them were based on designs by the USRA that were made in World War 1 until 1920. As well as a few other designs like the Decapods originally built for pre-Bolshevik Russia. But Lima would add many improvements to these engines to make them up to snuff with modern steam engines such as the Pennsylvania Railroad R3 and the New York Central J series Hudsons.
The first Lima standards were designed to be as modern as possible, and had all the features of such - roller bearings on all axles, integral cast engine bed frames that incorporated the cylinders, thermic syphons, Worthington feedwater heater and Walscherts valve gear. The larger designs also tended to have Belpaire fireboxes and Scullen Disc Drivers. Virtually all designs used double Kylchap exhaust systems as well. Well aware of the work of Andre Chapelon in France, Lima's design engineers indeed used many of the same theories and developments to conceive these engines.
Classification system
- Abbreviation for the arrangement's name
- Service purpose: "P" for passenger, "F" for freight, and "D" for dual service
- For example, a USRA Heavy Mountain was used as the basis for the MT-D
The DCL-F 2-10-0
- Based on the Russian Decapod
- Most Common User: St. Louis-San Fransisco (1633 Class)
The MK-F1 2-8-2
- Based on the USRA Light Mikado
- Most Common User: Western Maryland (N Class); Norfolk & Western (P Class)
- One of the WM types, #904, often runs excursions with other WM steamers on what is now the Wabash & Erie
The MT-D1 4-8-2
- Based on the USRA Heavy Mountain
- Most common user: Erie Railroad (L-1 type)
- Many ended up going to places like China, Africa, and Latin America (in my planned universe, almost all the railroads there are Standard Gauge)
The TX-F 2-10-4
- Based on the C&O T1
- Most common user: Pennsylvania Railroad (J1 type)
The HD-P 4-6-4
- Based on the C&O L Series
- Most common user: Union Pacific (FEF-2; FSF-1 was the CP engines)
- UP Painted theirs in a paint scheme based on that of the Challenger passenger train
The NT-D1 4-8-4
- Based on the unstreamlined Southern Pacific GS-2
- Most common user: Illinois Central (Class 3000)
